Efficacy of Telecardiology in improving the results of Cardiac Rehabilitation after acute myocardial infarction

BACKGROUND: This study was addressed to verify if Telecardiology (TC) improves the results of Cardiac Rehabilitation in patients following a home-based Cardiac Rehabilitation Program (CRP) after acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied three groups of patients after AMI: Group A (control group): 15 patients, who followed a standard in-hospital CRP of 3 weekly sessions of 2 months duration; Group B (study group): 15 patients, who were enrolled in a home-based CRP of similar duration and were monitored by TC with the aid of an ecg-device (Sorin Life Watch CG 6106); Group C (second control group): 15 patients, who followed a home-based CRP without ecg-monitoring by TC. All patients performed a symptom-limited exercise testing at the beginning of the CRP. Psychometric data (STAI-Y1, STAI-Y2, BDI) were also evaluated. At the end of the CRP all patients underwent repeated exercise testing and psychometric evaluation. RESULTS: TC applied to the home-based CRP was associated with a good compliance to the program. Compared to Group C, in Group B we observed an increase of maximal heart rate, exercise duration, maximal work-load, and an improvement of anxiety, a trend to reduction of depression, and an improvement of quality of life. These results were very similar to Group A patients following a hospital-based CRP. CONCLUSIONS: TC improves compliance, functional capacity and psychological profile of patients undergoing a home-based CRP, compared to patients enrolled in a home-based CRP without ecg-monitoring by Telecardiology.
